| Abstract | ||||
| Waste resulted from aluminum sulfate industry can be used as a source of silicate and aluminum. Such waste is called partial de-aluminated kaolin which is a solid waste. This work aims at utilizing such waste in the synthesis of some zeolites, Cancrinite and Chabazite-Na as two members of zeolite family were synthesized from It has been used as source of silica and alumina. Alumina ratio can be adjusted by adding aluminum sulfate. Cancrinite and Chabazite-Na were synthesized by heating partial de-aluminate kaolin for 2 h at 130 °C in autoclave. The hydrothermal system took 6–8 hours. However, 36 hours ageing at 70 °C was found to be synthesized Cancrinite and Chabazite-Na. The products were characterized using XRD and Sem . | ||||
